it also depends on whos 3.5 springs you run. REs3.5 springs give you over 4 inches of actual lift, where other brands might give you less. My RE 3.5 springs are 10 years old and the fronts have been carrying a full warn front end with bumper winch with 125' steel cable and they still are just over 4 inches tall.

You might want to check and see what your springs are actually sitting at. Factory springs sit at 12 inches tall so just subtract 12 from your current spring height and you get the lift in the front, i forget stock for the rear though lol.

2" Sus lift and 1.25" BL. I did have to trim the channel off in the rear wheel-well... Tube fenders may have helped. Not sure.
Definitely need to adjust bumpstops. And I chose to run extra long shocks so I need to outboard those eventually... havent gotten to it.
Oh and I put washers in the steering stops
